Colossendeis colossea is the largest pycnogonid in the North Atlantic; 
its bathymetric range off the eastern United States is roughly 500 
to 1,400 fathoms. It is a bright orange-scarlet in life. Though not 
so widely distributed as C. angusta, it is occasionally taken in greater 
numbers at individual stations. 
Disiribution.—Possibly a world-wide species of the deeper ocean 
basins.

Except for its smaller size, this species is very close to Colos- 
sendeis colossea and may be a dwarf variety of that species. Hoek’s 
specimen was taken by the Challenger at station 50 (lat. 42°08’ N, 
long. 63°39’ W; 1,250 fathoms, south of Halifax, Nova Scotia). The 
only intermediate form in the collection is a specimen from Albatross 
station 2725, in which the trunk and proboscis are as large as full- 
grown C. colossea, but the legs are about two-thirds as long. This 
appears to be an abnormal colossea and has been referred to that 
species. The specimens identified as C. minutea are perfectly pro- 
portioned, and at least one (Albatross station 2735) appears to be 
mature. This specimen is about 25 cm. in extent which is about 
half the size of the average C. colossea.
